Designed to deliver ultra-high quality images along with lightning fast
operation, the new Canon EF 70-300 f/4-5.6L IS USM telephoto zoom lens
brings a favorite zoom range to the celebrated Canon L-series of lenses.
It features two Ultra Low Dispersion (UD) elements for improved image
quality and reduced chromatic aberration, incorporates a floating
focusing mechanism for sharpness from close up to infinity, plus an IS
system that increases usability by approximately four stops. The Image
Stabilization system also features a function that allows it to continue
to operate, even when used on a rigid tripod. Gleaming white on its exterior, the lens is dust-
and water-resistant, and now also features a newly-developed Fluorine
coating that resists smears and fingerprints, and significantly eases
lens cleaning. For any serious and critical EOS user, this new L-series
lens represents an excellent -- and portable -- solution to versatile
telephoto lens shooting.
